A record disposition system classifies records into disposition groups based on an expiration date or disposition date of the records. For each disposition group, the system generates an encoding and decoding function. An encoding module uses the encoding function associated with the disposition group of a record to transform a record locator in an index entry associated with the record. To obtain the record from the index entry, a decoding module decodes the transformed record locator using the corresponding decoding function. The decoding function is stored to allow it to be individually disposed. When a disposition group of records are disposed, disposition of the associated decoding function is also carried out. A record locator in an index entry identifies a block in the expiration control block that identifies a corresponding record. In another embodiment, the encoding function includes an encryption algorithm.
